(NASDAQ: SLS) (“SELLAS’’ or the “Company”), a late-stage clinical biopharmaceutical company focused on the development of novel therapies for a broad range of cancer indications, and GenFleet Therapeutics (Shanghai), Inc. (“GenFleet”), a clinical-stage biotechnology company developing cutting-edge therapeutics in oncology and immunology, announced today that the companies have entered into an exclusive license agreement that grants rights to SELLAS for the development and commercialization of GFH009, a highly selective small molecule cyclin-dependent kinase 9 (“CDK9”) inhibitor, across all therapeutic and diagnostic uses worldwide outside of Greater China (mainland China, Hong Kong, Macau and Taiwan). GFH009, currently in Phase 1 clinical trials in the United States and China, is a highly selective next-generation CDK9 inhibitor. CDK9 activity has been shown to negatively correlate with overall survival in a number of cancer types, including hematologic cancers, such as acute myeloid leukemia (“AML”) and lymphomas, as well as solid cancers, such as osteosarcoma, pediatric soft tissue sarcomas, and melanoma, and endometrial, lung, prostate, breast and ovarian cancer. As demonstrated in pre-clinical and clinical data, to date, GFH009’s high selectivity has the potential to reduce toxicity as compared to older CDK9 inhibitors and other next-generation CDK9 inhibitors currently in clinical development. The Company believes, based on the initial pharmacokinetic data of the ongoing Phase 1 dose-escalating clinical trial, that the administration of GFH009 leads to lower toxicity and more potent efficacy due to its unique mechanism of action. Thus far in the Phase 1 clinical trial, which is planned to enroll approximately 80 patients, including an expansion par...
